Cold water currents are more likely to be in deep ocean than water water currents because

• ocean tides force cold water downward

• Winds push the cold water down

• cold water has less salt to help it freeze and sink

• cold water is more dense and sinks

Warm water currents affect coastal areas near where they flow by doing what?

• creating greater rainfall along the coast

• creating unusually warm climates for the latitude

• creating unusually cool climates for the latitude

• making coastal climates cooler than the inland climate

What causes the temperature difference between cities on CA's coast & cities in Arizona?

• a cold water surface current off California’s coast

• the shade provided by the large number of trees in CA

• winds formed high in California’s mountains

In the Northern Hemisphere, winds traveling north appear to curve to the east because of

• Coriolis Effect

• convection currents

• polar easterlies

• trade winds

What causes convection currents in Earth’s atmosphere?

• heat from Earth’s core heats the land only at the equator

• glaciers moving away from the poles cool Earth unevenly

• sunlight is more concentrated in some places on Earth

• the light & heat reflected varies as the Moon changes phases
